Research on the Farm – Barley Seeding Rate Trial Summary

Manitoba Crop Alliance’s (MCA) Research on the Farm (ROTF) program conducts scientific research with farmer members using replicated strip trials on commercial fields. Farmer co-operators use their own equipment and management practices to conduct this research. Research projects are developed to investigate current and pressing agronomic questions and provide site-specific answers. More information about the ROTF program and all trial results can be found here.

Barley genetics for both malting and feed varieties have improved over the last decade. Evaluating current seeding rates for new barley varieties was necessary to understand if target plant stand densities are optimized for both grain yield and quality. The purpose of this trial was to investigate the economic and agronomic impact of farmers increasing and decreasing their target plant stands. This was done by having decreased and increased seeding rate treatments compared to the farmers’ normal.

Over the past three years (2022-24) MCA conducted 17 barley seeding rate trials. Throughout the trial period, seeding rates ranged from 78-225 lb/ac. Eleven sites planted feed barley and six sites planted malting barley. CDC Austenson (feed) and AAC Connect (malting) were the most planted varieties
